Problems solved by technology

[0003] Black reactive dyes are the most widely used and produced varieties of dyes. At present, most of the dyes used in the market are compounded by adding orange components to C.I. reactive black 5, but there is still a color fixation rate in the dyeing process. It has low dyeing and deepness, and there are also problems such as poor washing performance and serious color sticking

Embodiment 1

[0036]Mix 80 parts of the dye of formula (1), 20 parts of the dye of formula (2), and 1 part of the dye of formula (3) and then fully mechanically mix to obtain the composite reactive black dye of the present invention. This dye can print and dye fiber material fibers. High level dyeing, high fixing rate, high jet black fullness and good dyeing depth.

[0037]Dip dyeing: respectively, 1g of the dye prepared according to Example 1 is first fully dissolved with an appropriate amount of water, and then the volume is fixed to a 250ml volumetric flask, and 50ml of dye solution is mixed with 50ml of water, and then 5g cotton cloth and 6g sodium sulfate are added. Then increase the temperature to 60°C at a rate of 1°C / min, keep for 30 minutes, add 2g of sodium carbonate, keep at 60°C and dye for 30 minutes, then take out the dyed cotton cloth and boil it with a non-ionic detergent for 15 minutes, then wash with water. Dry at around 70℃.

Abstract

The invention belongs to the technical field of dyes, in particular to a composite reactive black dye, comprising a dye shown in formula (1), a dye shown in formula (2) and a dye shown in formula (3), in parts by weight The proportioning ratio is as follows: 50-100 parts of the dye of the formula (1), 5-45 parts of the dye of the formula (2), and 0-5 parts of the dye of the formula (3). The present invention also provides a black dye composition, including a color-fixing alkali agent, a dyeing accelerator and the above-mentioned composite reactive black dye. The composite reactive black dye provided by the present invention has higher dyeing depth, good color fixation rate and washing performance, and low raw material cost. The compounding of the three dyes of formula (3) makes the dyed fabric have higher level dyeing property, high color fixing rate and high fastness, and achieves unprecedented jet-black fullness and dyeing depth, and increases the washability of the dye It solves the problems of poor washability and serious color sticking of existing reactive black dyes, and is suitable for exhaust dyeing, pad dyeing and resist printing of fiber materials.

Description

Technical field[0001]The invention belongs to the technical field of dyes, and specifically relates to a composite reactive black dye and its application.Background technique[0002]In recent years, composite dye technology has developed rapidly, and composite reactive dyes have become more and more widely used. Mixing different reactive dyes can play a synergistic effect.[0003]Black reactive dyes are a variety of dyes with more applications and larger yields. At present, most of the dyes used in the market are compounded by adding orange components to CI Reactive Black 5, but they still have a fixation rate during the dyeing process. It has low dyeing depth, poor detergency and serious color sticking.Summary of the invention[0004]In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a composite reactive black dye and its application, which not only has low production cost, high dye depth, good color fixation rate, h...
